IMPROVEMENT IN'JOURNALBOXES.

Specification forming part of Letters Patent No. 133,472, dated November 26, 1872.

my invention; and Fig. 2 represents a crosssection through the same.

In addition to the process of welding brass, or alloy of copper, to iron or steel, and the manufacture of journal-boxes'having iron or steel backs, and a hard brass lor bronze lining,

made by such process, I have also discovered that a journal-box may be made with some degree of economy and of great value without using either an iron or steel back, and which would avoid one of the incidents that such iron or steel backs are liable to-namely, al

lowing the iron or steel of the journal or axle, by long and great wear, to come in Contact with the iron or steel back of the journal-box, which would cause them to heat, clog, and fracture, and cause accident.

My present invention consists in a new article of manufacture, viz., a journal-box in which the back, which is the strengthening part of' the box, is made of soft, tough bronze, and the lining or wearing part made of bell metal; and by bronze and bell metal are meant certain alloys of copper well known to those skilled in the art to which they pertain.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawing, first premisin g that, as both the back or tough metal and the lining or hard metal are used in a iiuid or molten state, it is immaterial whether the lining be flowed into, and so welded to the back, or whether the lining be rst made and the metal to form the back be flowed onto, into, or over such lining; either way will answer, but the union of the two metals is made by flowing or casting one of them in a molten state onto the other in a hardened condition by being cooled or less heated.

In the drawing, A represents part of a journal-box of any suitable shape, size, or form,

and furnished with Vsuch recesses, flanges, or shoulders as may be required. The back or tough-metal portion of the box is shown at a; the lining or hard-metal portion is shown at b. The line of weld or union between these two metals, though distinctly marked by a line, c, in the drawing, is not so in practice, as one metal, the molten one, seems to run into, over, andaround the surface of the other metal so as to form a very visible but not regular line of union. The metals seem to fuse and change places at the line of union, and to leave no semblance of a crack or unwelded portion.

A journalbox thus made of brass or bronze-one part tough for strength, and the other part hard to resist wearing, and these two parts` fused or welded together by pouring one metal onto or over the other metal, though more expensive than those with an iron or steel back and bell-metal lining-possesses a qualitywhich the latter does not, viz., it does not lie open to the objection that, after long use, an iron or steel back and an iron or steel axle are liable to come together without notice. Besides, the all bronze or brass boxes, of two metals of different consistencies, as above described, have equal strength with those that have iron or steel backs, and may be repaired, or the remaining metal, after the boxes are worn out, reused to greater advantage than those having iron or steel backs.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, as a new article of manufacture, is

A journal-box, composed of a tough-bronze back for strength, and a bell-metal or hardbronze lining to resist wear, said two metals being united byvpouring one in ainolten state upon the other, substantially as described and represented.
